Because Big Sister Says So!

[PrincepsCyberius]

Gus caught a nice glimpse of Dawn's firm, apple-sized breasts, their dark pink areolas crinkled and nipples erect with excitement. Then she returned to his arms and resumed their passionate French kissing.

Gus's erection bulged under his black wool slacks and he could not remember the last time he felt such need for a woman. To the small extent he remained aware of their audience, he cared not at all. Indeed, if he paused to take Dawn to another room, Cathy might intervene with plans of her own. He wanted Dawn desperately and without delay.

Breaking their kiss, he traced with his lips down the smooth alabaster skin of her neck, shoulder, and left breast. Reaching the stiff nipple, he took it into his mouth and flicked his tongue upon it. Bending down to do this parted their hips from one another and he took advantage of the space to unbuckle her belt and open the button and zipper of her tight white corduroys.

"Oh Jesus..." Dawn groaned as Gus sucked and licked her nipple. Despite her somewhat narrow hips, he seemed to struggle pushing down her tight corduroy slacks. She did not want him to get too far ahead of her anyway, so she backed away until her breast popped out of his mouth. Before he could straighten up, she reached down and pulled his blue sweater and white T-shirt off over his head. As he stood straight, she sighed with desire seeing that, despite a semester of college, he maintained the lean, muscular body he'd developed as a swimmer and from working at his father's lumber yard.

Locking her gaze onto his eyes, yet fully aware of the three women watching from the kitchen, she reached down and pushed off and stepped out of her slacks so she posed before him, and them, in just her panties and knee socks. She wondered how the three sisters, especially Marie, saw her body. She stood nearly a head taller than all of them. So where their slenderness made them petite, it made her svelte and willowy.

In any case, she loved Gus's reaction. He tried to hold his head steady as his eyes roved up and down her body. She saw his vision linger at her breasts and shifted her weight just enough to make them sway slightly. When he finally raised his stare back to her face, she blatantly began looking down his body, stopping when she saw the way his erection pushed forward the front of his pleated black pants.

Moving almost by instinct, Dawn dropped to her knees in front of him and began unbuckling his belt. She had never seen a man's erect organ before and could not wait to see this one. With his belt open, she carefully began to unzip his fly.

Now confident where this kinky reunion of Gus with his ex-girlfriend Dawn would lead, Cathy looked across the kitchen to where Gus's current girlfriend, Cathy's sister Marie, held hands with their younger sister Casey. Both stared intensely at the couple as Dawn and Gus slowly undressed each other. Casey looked slightly angry while Marie remained attentive but outwardly emotionless.

Cathy raised her hand a bit to draw her sisters' attention. When they looked her way, she first held her index finger to her lips to indicate they should remain silent. She pointed then crooked her finger at Casey, summoning her to her side.

 

[DawnONight]

Gus did not move or otherwise react as Dawn opened his belt and unzipped his fly. With the zipper parted, the shaft of his penis bulged out in a curve, restrained by the white cotton of his briefs. Dawn hesitated, unsure if she really wanted to do this now and here. She sensed some movement from the kitchen, but no one spoke. Dawn did not look, but assumed the sisters all watched, wondering if she would go through with this display.

This made her realize that if she stopped now it would look like she had chickened out, revealing her as an indecisive and inexperienced virgin. That decided the matter. She would not give Marie that victory.

She found the waistband button above Gus's open fly and despite her trembling fingers managed to slip it through the buttonhole. The front of his slacks fell open allowing his erection to push out even further. With the slightest tug, his slacks fell down around his ankles.

Her hands went to Gus's hips and she hooked her fingers over the elastic waistband and pulled his briefs down past his knees with one tug. As soon as it cleared the fabric, his stiff organ sprang up, lightly striking her left cheek. She squealed in surprise and sat back on her heels.

Dawn had never before seen an erect penis. She found it both intriguing and beautiful. She marveled at how it seemed to defy gravity. The bulging blue veins meandering up its length looked sculpted, as did the mushroom-shaped head. At least a couple inches longer than her six-inch vibrator, Gus's shaft likewise exceeded the toy's circumference noticeably. Dawn felt her already damp womanhood get wetter as she thought of him entering her with it.

First, however, she wanted to show her sexual sophistication and presumed possession of this prize to Marie and her sisters. The shaft felt warm as she carefully wrapped her right hand around it. Leaning forward, she took the head and about an inch of the shaft into her mouth, tasting a salty drop from its tip as she swirled her tongue around it.

Gus gasped as much from surprise as pleasure when Dawn took his penis into her mouth. When they had dated, they had never gone further than touching each other through clothing. Now, not only had she taken their necking quickly to felatio, she did so in front of Marie and her sisters.

Gus resisted the temptation of turning his head to look into the kitchen. He could not imagine meeting Marie's gaze at this moment. Instead, her simply closed his eyes and enjoyed the intense pleasure of Dawn's soft hands and limber tongue on his erection.

Now standing next to Cathy, Casey could barely believe her eyes. Their sister Marie's boyfriend Gus stood in their living room publicly accepting oral sex from his previous girlfriend Dawn. Casey fely simultaneously horrified at the concept, amazed at the event, and impressed with its architect, Cathy, to whom she now whispered.

"You have really outdone yourself this time Mistress. How did you know this would work?"

 

[CCorteeze]

"You have really outdone yourself this time Mistress," Casey told Cathy, the admiration heavy in her voice. "How did you know this would work?"

In truth, Cathy hadn't known inviting Gus's ex-girlfriend to join their kinky adventure would work. She had done it on a whim in the flush of hubris brought on by displaying her slaves in public. Had she given the idea much forethought, she would never have risked upsetting the delicate balance of relationships she had already managed among herself, her sisters Marie and Casey, and Marie's boyfriend Gus.

Cathy loved but had for years slightly resented her younger sisters. She considered Casey the prettiest of the three of them and she envied her abilities as a musician and dancer. Casey played guitar, sang sweetly, and had captained their alma mater's state champion pom-pom squad. Meanwhile, not only was Marie the smartest of the three of them and a talented artist, she was so far the only one to have a long-term steady boyfriend, Gus.

Thus, after seeing Dawn's reaction to Marie's collar at the restaurant, Cathy desperately wanted to humiliate her sister further. Sensing Dawn's curiosity, she had invited her to dinner, thinking how it would shame, belittle, and demean Marie to serve Gus's ex-girlfriend as a slave. At the time, she had given it no more thought than that.

She would not, however, admit this to Casey. As Mistress, she must appear fully confident, competent, and in control. She smiled at Casey and replied enigmatically.

"Because knowing such things is what a Mistress does. Never underestimate what I can do, Slut." She turned to study Dawn's clumsy and tentative fellatio upon Gus's lovely full erection. She did not want the newcomer to falter or grow shy now that things had progressed so quickly. She weighed two possible approaches to the situation and decided that direct action always made more sense than leaving things to chance through inaction. She turned back to Casey and whispered. "I think Dawn may be a virgin. Get over there and guide her along. And make sure she comes before they're through. I want your sister to watch Gus give his ex an orgasm."

 

[DawnONight]

It would not have surprised Dawn if her ex-boyfriend Gus had pushed her away when she started giving him oral sex right in front of his current girlfriend Marie and her sisters. Instead, he simply gasped and allowed her to proceed.

She proceeded as best she could. She had never actually done this before. She had at best approximated the act using her saliva to lubricate the vibrator her older sister had given her to fill lonely evenings since Gus dropped her.

At first, she tried to take it all into her mouth, but almost started to gag. Then she moved her head back and forth, as if making love. She worried, however, that this might scratch him with her teeth.

So she explored him with her tongue. She swirled it around the ridge defining where the head met the shaft. She ran it back and forth upon the bottom, top, and all around its length. She even pressed its tip against the little slit opening. With each technique, she took note of his reaction so that she could hone her oral repertoire to what Gus liked best.

 

[KaseE]

"I think Dawn may be a virgin," Cathy whispered conspiratorially. "Get over there and guide her along. And make sure she comes before they're through. I want your sister to watch Gus give his ex an orgasm."

Blushing slightly for the plot to humiliate Marie, but now too invested in and excited by the plan to hesitate, Casey softly tiptoed behind Dawn where she knelt before Gus, giving him oral sex in the middle of the living room. She only saw Dawn's lovely long brown hair brushing across the alabaster skin of her nude back as Dawn's head bobbed up and down on his erection. She pictured, however, Dawn beautiful face, broad and bright smile, cute little nose, and sparkling blue eyes. The thought that she might soon share intimacy with this beauty made Casey's now damp womanhood twitch with desire.

"Just relax," Casey implored softly as she lowered herself slowly to her knees behind Dawn and placed her hand's gently on her smooth shoulders. "I can guide you through this."

 

[DawnONight]

Focused on orally pleasing Gus, Dawn did not hear Casey step up behind her.

"Just relax," Casey whispered. Nonetheless, Dawn's whole body twitched and she gasped around Gus's thick erection when she felt Casey's hands softly come to rest on her shoulders. Casey reassured her. "I can guide you through this."

Dawn had never felt a caress so sublime as when Casey's hands began to move upon her skin. Already sexually aroused by having Gus's stiff organ in her mouth, each of Casey's fingers felt like a source of warm electricity that went tingling through Dawn's body to settle torridly in her loins. Lust surged through her and she sucked the hard shaft deep into her mouth and moaned wantonly upon it.

 

[PrincepsCyberius]

Gus's eyes snapped open at the sound of Casey's voice and the feel of Dawn's gasp around his erection. He looked down to see Casey kneeling behind Dawn, starting to caress her shoulders. He had no doubt that Cathy had required Casey to join them. For a moment, he worried that Cathy might have rushed things. When he had dated her, Dawn had never given any hint that she would have any interest in lesbian intimacy.

Then he heard Dawn's lusty moan as she took him deeply into her mouth. Somehow, Cathy had guessed correctly as to how Dawn would react. He continued to gaze down at the two lovely women kneeling before him. He would surely enjoy seeing what Casey did to Dawn while the latter continued to give him fellatio.

 

[KaseE]

Casey smiled, finding a pleasant surprise in Dawn's lusty reaction to her gentle caresses upon Dawn's shoulders. She had hoped for no more at first than indifferent tolerance. She wondered if Dawn's passionate receptivity to her sensual petting revealed simply general concupiscence or, in fact, a latent but emerging bisexuality.

In either case, Dawn's muffled moan encouraged her to proceed brazenly. Instead of massaging her back, as originally intended, Casey moved her hands gently forward, softly stroking down Dawn's pert breasts to lightly brush her nipples.

 

[DawnONight]

"Ahh Gact!" Dawn groaned involuntarily around Gus's erection already deep in her mouth. The feathery caress of Casey's soft fingertips down her breasts and across her nipples made her shiver despite the heat rising from her loins. Her right hand remained around the base of Gus's shaft, but she could not resist slipping her left hand between her thighs and touching herself. Again she moaned as her middle finger parted her sodden folds. She did not think she had ever before been this wet.

 

[KaseE]

Casey's smile broadened, her boldness in caressing Dawn's breasts encouraged by the newcomer's wanton moans. She fondled them with increasing vigor, stroking and kneading them and rubbing the nipples. Dawn continued to respond positively and Casey could tell by the angle of her left arm that she had started to touch herself with her free hand as she continued to stroke and suck Gus's hard penis. Giving Dawn's breasts an especially tight squeeze, Casey whispered into her ear.

"You are about to have the best night of your life!"

 

[DawnONight]

"You are about to have the best night of your life!" Casey's whispered promise felt pleasantly warm in Dawn's ear as the speaker gave Dawn's breasts a delightful squeeze, then resumed fondling them and rubbing her nipples. Dawn's left hand remained purposely between her own thighs as she continued to touch herself. A habitual masturbater, she automatically began to spread her copious juices up to her clitoris, gasping in pleasure the first time she stroked it.

With her eyes closed and focused on the joy Casey's and her own hands gave her, she had almost forgotten about Gus. Her sudden intake of breath around his erection triggered an involuntary twitch forward of his hips, almost gagging her. She pulled her head back a bit and, as she began to swirl her left middle finger around her now slick clitoris, she did the same with her tongue around the engorged head of his penis.

 

[PrincepsCyberius]

The cool air drawn over his wet erection by Dawn's gasp caused Gus to involuntarily thrust his hips. He felt its tip hit the back of Dawn's throat and how she pulled back as a result. He opened his eyes and looked down to apologize, but saw she currently experienced anything but distress. Her face exhibited pure bliss, despite having to stretch her lips around his thick shaft.

He could see the muscles of her left forearm flexing as she played with herself with the hand between her thighs. Meanwhile, Casey had started to more aggressively fondle Dawn's breasts and nipples. Suddenly, Dawn stopped moving her tongue randomly all over Gus's stiff organ and began simply swirling it around its firm head. He moaned with sensual approval.

"Oh god.... Yes... just like that...."

 

[DawnONight]

"Yesss," Gus groaned passionately. "Just like that...."

With her focus inexorably drawn to the rising pleasure from Casey's and her own fingers upon, respectively, her nipples and clitoris, Dawn had to pause and concentrate a moment to remember that she had streamlined her oral technique to simply swirling her tongue around Gus's firm erection head. Hearing how this pleased him, she quickened the speed of these lingual acrobatics. Unconsciously, this acceleration impelled her left middle finger to increase its rate of twirling upon her slick clitoris. Now Dawn moaned wantonly around her whirling tongue as she began performing fellatio and masturbation at an increasingly frenzied pace.

 

[CCorteeze]

Cathy heard Dawn's muffled moans and saw the muscles in her forearm flexing at an increasing pace as the girl fingered herself with growing desperation. At least it had not yet caused her to lose focus and stop sucking and licking Gus's large erection. This degree of concentration by the novice actually surprised Cathy a bit, given the added distraction of Casey kneeling behind Dawn, fondling her breasts, rubbing her taut nipples, and nuzzling the side of her neck. Wanting to maintain control of the situation, Cathy glided into the family room and crouched down next to Dawn

"Slow down, Sweetie," Cathy whispered soothingly. "You don't want to come yet. Wouldn't you rather come making love to him?"

 

[KaseE]

Snuggled up behind Dawn, Casey heard what Cathy whispered into the newcomer's left ear. To help Dawn comply with her Mistress's wishes, Casey moved her left had down off of Dawn's left breast --- her right hand continued to caress and fondle the other one --- and pulled Dawn's hand from out between her thighs. Casey then slipped her hand in to replace it. Where Dawn had just been frantically rubbing her own clitoris, Casey lightly stroked and teased it, causing Dawn to whimper in frustrated desire around Gus's erection still filling her mouth.

"Trust the Mistress and me," Casey cooed into Dawn's right ear. "We'll make sure you have an orgasm better than you ever imagined possible."
